NASA Considers Apollo-Era F1 Engine For Space Launch System 197

Posted by Soulskill on Saturday July 28, 2012 @08:08PM from the what's-old-is-new dept.

MarkWhittington writes "A company named Dynetics, in partnership with Pratt & Whitney Rocketdyne, will perform a study contract for NASA to explore whether a modern version of the Saturn V F1 booster (PDF) could be used on the Space Launch System. These would be the basis for a liquid fueled rocket that would enhance the SLS to make it capable of launching 130 metric tons to low Earth orbit, thus making it capable of supporting deep space exploration missions in the 2020s."

It's cool, but I suspect a large proportion of those who have diabetes is due to lifestyle choices - obesity, in particular, increases your risk of adult-onset diabetes. Let's see more research in areas that are less profitable but more "equitable" in benefits to folks worldwide.

If you add the word "fiction" to science, the Science Fiction and Fantasy Museum in Seattle is pretty awesome. Otherwise, consider trying to catch a meteor shower - they're often better-documented re: ideal viewing times in the US.

I think a point can be made that today's orchestras are rarefied places. If you consider orchestras and classical musicians, say, during the 17th-19th centuries - when the market was much larger, perhaps more like today's computer science field - it may be a more apt analogy re: depressing the market with a flood of sub-par graduates.

Living in Thailand this winter has destroyed any sense winter even happened. Banana trees plus Thanksgiving dinner almost made my head explode.

Submission + - TI Against Calculator Hobbyists ... Again (omnimaga.org)

Submitted by Deep Thought on Saturday July 17, 2010 @08:48PM

Deep Thought writes: Texas Instruments, already infamous thanks to the signing key controversy last year, is trying a new trick to lock down its graphing calculators, this time directed toward its newest TI-Nspire line. The TI-Nspires were already the most controlled of TI's various calculator models, and no third-party development of any kind (except for its very limited form of TI-BASIC) was allowed until the release of the independent tool Ndless. Since its release, TI has been determined to prevent the large calculator programming community from using it. Its latest released operating system for the Nspire family (version 2.1) now prevents the calculators from downgrading to OS 1.1, needed to run Ndless. This is the TI's second major attack on Ndless, as the company has already demanded that websites posting the required OS 1.1 be removed from public download, obviously to prevent use of the tool. Once again, TI is preventing calculator hobbyists from running their own software on calculators they bought and paid for. Is TI going the way Apple did?
